SAFETY DEVICE FOR RAILWAY-CARS,

Specification of Letters Patent.

Patented Sept. 13, 1910.

Application filed June 1(?, 1910. Serial No. 567,172.

' and a resident of Waterville, in the county of Kennebec, State ofMaine, have invented certain new and useful Improvements in SafetyDevices for Railway-Cars, of which the following is a specification.

My invention relates to a safety device for railway cars andparticularly to certain improvements in the device shown in my LettersPatent No. 926,334, dated June 29, 1909. i 3

In my patented device, a shaft was journaled beneath the car andlongitudinally thereof and a relief valve on the train pi )e was openedby the rotation of this shaft. The shaft was rotated and the train pipeopenedin case of the derailment of the truck by an arm which projectedout from the truck and was arranged to strike a bar which ranlongitudinally of the car below the truck frame extending practicallythe whole length of the truck. This bar was in such a )osition that itwas liable to be accidentaly struck, thus stopping the train when notnecessary.

According to my improvement I ell'ect the rotation of the shaft by atransverse horizontal member located above the truck and in a positionwhere itwill not he accidentally struck.

Other features of improvementare covered in this application as fullyset forth in the following specification.

I illustrate my invention by means of the accompanying drawing in whichFigure l a side elevation of a car equipped with my improved safetydevice, and Fig. 2 is an end elevation of the same.

In the drawing, A represents the car body, B the wheels, I; the journal-boxes, the shaft, fl. the train pipe and It the branch on which is therelief valve i These )arts are all common to my prior patent and requireno further description.

\For the purpose of rotating, the shaft. (1

when the truck drops down by reason of derailment or otherwise, Iprovide a transverse horizontal member which is depressed by an uprightsecured to the truck.

As here shown, I make use of a horizontal member or lever d pivoted toa. hanger beneath the car and extending transvm-scly of the length ofthe car directly above each wheel. Cooperating with the lever d is anupright shown as an inverted U-shaped strap f secured to the journal boxand embrac ng thelever (Z.

Considering the left hand side of Fig. 2, the lever d is connected atits end with an arm 0 on the shaft C by means of a link 0 so that whenthe lever d is depressed, the shaft (,1 will be rotated.

On the other side of the car the lever d is connected with an arm a onthe shaft (1 by means of a link 0 but the connection is made on theinside of the hanger" which suports the shaft so that the depression ofthe ever d will tend to turn the shaft in the same direction as theshaft 0 on the other side of the car is turned. Since the motion of eachshaft is transferred to the valve F, this arrangement is necessary. Themotion of each shaft- C is transferred to the handle 7 of the reliefvalve by telescoping rods each of which operates independently of theopposite one.

On the left hand side (Fig. 2) the arm E depeluling l'ronfthe shaft (1is pivoted on the end of a rod (1 having, a loop r ol'l'set at its innerend and engaging the rod 0. The rod 0' connects with the valve handle fand has aloop c embracing the rod 0. A stop 6 on the rod abuts normallyagainst end of the rod 0. Thus when the rod e is forced inwardly it actson the rod and throws the valve open but when the valve is opened fromthe opposite side, it simply elongates the telescoping rods r. c-'without disturbing the adjustment of the safety devices on that side ofthe car. A similar arrmigemen't on the right. hand side of the carprevents the safety device being disturbed when the opposite side isoperated.

A rod w. has a loop a at its end embracinga rod it connected with thevalve handle, this latter rod lnuing a loop a" embracing the rod n. Astop on the rodn allows the connection to telescope inward while a pulloutward has the effect of turning the valve handle.

l t sometimes happens that the brakes and brake beams fall down and socause damage to the car and l ,have provided safety means connected withmy attachment for stopping, the train when this occurs. For this pur--pose, I make use .of a horizontal cross ba as i which extends across thecar from one side to the other. This bar is suspended by links 2' at itsends from arms 2' on the shafts G. The bar 11 is depressed when thebrake beam drops by an upright i secured tofthe brake beams j andengaging the cross bar Thus when the brake beam falls, the bar 7. isdepressed, the shafts C revolved and the relief valve opened.

The shaft 0 is prevented from accidentally turning by a spring m fittinga recess in a cam m on the shaft O,.(shown only On left side of Fig. 2)but such a connection is liable to become displaced and in order to holdthe shaft more positively, I secure the transverse member 03 to the bodyof the car by an easily broken tie rod 05 which breaks under anexcessive strain in case of accident to the car. The liability of havingthe apparatus accidentally sprung is thus reduced to a minimum.

It will be seen that the lever d is directly over the shaft 0 and incase the journal breaks allowing the journal box, to drop down, thetruck will be held up by thestrap f and lever d. When the truck isderailed and drops down on either side, the relief.

valve is opened as in the case of my original device, and also when thebrake beam falls. Thebarz' is also located directly below the draw-barand if this falls down it strikes theba-r '2". and operates the devicestopping thetrain. v

The device as I have here'shown it {can be cheaply a plied to. a car, itis out, of be way of the ot er parts and is effective in preventing alarge class of accidents. vI

It is evident tha'tthe upright may act directly 01 the arm a rather thanonthe lever 05 but I prefer to make use of a transverse memberindependent of the shaft.
